[feature] Git sync

[ivicac]

As a Workflow Developer

I want to store workflow definitions in Git

So that I can back it up and also have, if required, a fully CI/CD development cycle

Acceptance Criteria

• [ ] support for Git
• [ ] support for GitHub
• [ ] support for GitLab

Definition of Done TODO

Technical details:

• Sync should be two-way:
  1. Git -> ByteChef - ByteChef pulls for changes
  2. ByteChef -> Git- ByteChef pushes for changes
• There is already support for reading from git
